Schematic structure of cardiac troponin I.
A: Structure of cardiac troponin I with the location of the mutations identified in this study indicated. B: Schematic structure showing interactions among troponin I, troponin T, and troponin C in the calcium saturated thin filament. Cardiac troponin I is marked in red. α-helices are shown with cylinders (Wang et al. 2012).
